task switcher. Simply click on the app that you want to bring to the fore.
Tap the pie chart on the left to bring up the App Manager. Below you can
see the option to view the amount of disk space used.

The On-off Button
The on/off button is on the right side, about 3/4 of the way up.
Long press it to bring up a screen to:

When the screen is locked, the phone is still active, but the screen is black

On some devices, such as the Galaxy S4, you can switch from Standard Mode
to Easy Mode. Go to:
- Settings | My Device | Home Screen Mode
- Choose Easy Mode or Standard Mode
Here are some examples of Easy Mode. All the other screen shots on this page
unless explicitly stated otherwise, are of standard mode.
Here is the Home Screen in Easy Mode. Notice that there are now just two
panes in addition to the Home Screen. See the little icons at the very
bottom of the screen? They show icons for the home page, and the two panes.
Here is the pane located to the right of the Home Screen:
Galaxy S4 Sensors
